    【Abstract】 Objective To improve the rate of accuracy and positiveness in diagnosis of onychomycosis, and to explore new approaches.Methods 61cases of suspected onychomycosis were tested by KOH-treated nail clippings, and compared with direct microscopic examination, fungal culture, histopathologic examination. Results The positive rate of KOH-treated nail clippings was 86.89%, and was also higher than other approaches.Conclusion KOH-treated nail clippings is a reliable method that has proved high positive rate. ......
